osnonmornnonxv rnn,new YORK OIL STILL My invention relates more particularly. to

- oilstills of the kind commonly employed for straightdistillation, cracking, etc., in which the bulk of oil to be treated is charged into a boiler or still proper, arranged in a suitable furnace and heated therein until the desired amount of the lighter components of a still of this character- After a run has been completed, there remains in the bottom of the still a bed of coke containing more or less other solids and, depending on the extent to which the distillation is carried,

an overlying body ofheavy, tarry material,

** and it is'the common practice for workmen to enter the still after it has cooled down through a manhole provided in the end of the shell, and to shovel coke, etc. out through themanhole so that the shell ma be practically empty and clean before it is again charged with oil to be distilled. The shell 7 the main line.

is ordinarily provided with a suction and charging line entering through the top of the shell and extending nearly to the bottom thereof. This line is ordinarily used for charging they still with oil but is sometimes used, with an appropriate suction pump, for removing oil or tar therefrom. In order to permit the workmen to properly and conveniently clean out the still, it has been the practice to make the lower end of the suction and charging'line within the still of a separate section, providing such section and sthe lower end of'the main portion of the charging line with flanges, drilled with a number of holes, by means of which the lower removable section of the line can be secured to and released from the lower end of Before the cleaning out operation, the lower detachable section is removed from the shell after releasing the bolts by which it is secured to, the main sectionof the charging and suctionline and, after the cleaning operation is completed,'th'e removable line section is again bolted to the main lower end of the suction and charging line. In ordinary practice, the still shell is of adiameter of 12 to let feet and the removable section is about 6 feet long, 6 inches in diameter and weighs considerably over 100 pounds. lVhen this pipe section is being attached or detached, the operation requires, in addition to the workman manipulating the bolts, a second workman tohold the removable section in position until completely detached or attached, as the case. may be. The time required for this operation is quite considerable, putting. a great strain on the workman holding the removable section in position and it has. frequently happened that the workman has dropped the pipe and, in {)nany instances, been seriously injured there- ;It is the purpose of the present invention to so connect the'detachable section to the main section of the charging line that a single workman can manipulate the detachable section to remove it out of the way of the operatives who are to clean out the still and to dispense with the services of the second workman and, obviate the dangers above-mentioned. With this object in view, instead of forming the lower section completely detachable,'I hingeit to the main section of the charging and suction line and provide means whereby it maybe swung up out of the way of thOSe engaged in cleaning out the still and securely anchored until the cleaning operation is completed and then readily returned to operativeposition and secured therein. Other more specific features of my invention will appear from the drawing and the detailed description below.

' In the drawing accompanying and forming a part'of this specification, Fig. 1 is a vertical axialsection through a shell of a still to which myinventi'on has been applied; Fig. 2 is an enlarged fragmentary view, inside elevation, of the meeting ends of the two sections of the l charging andsuction pipe; Figs. 3 and 4 are plan views of details.

Referring to Fig. 1 of the drawing, the

holes with their removable cover plates at 3 and 4. It has not been thought essential to 11- lustrate either the furnace setting or the con-' densation apparatus, as they may be of any The lower endof the vaporline is shown at 5. v

V The lower end of. he ma 7 portion of the discharge and suction pipe is shownat 6 and the lower end thereof, Within a the still, is formedor provided with a flange 7 drilled at suitable intervals as at8 for the reception of bolts. The flange is also formed witha lugor ear 9,perforated at 10 for apur- V pose which will appear; The movable sec:

tion 'll of the suction and charging pipe is V formed or provided at its upper endwith a 1: corresponding perforated flange 12, from "or stationary my name 3. In an apparatus of the class described, V

a'still' shell, a charging and suction line extendinginto the shell throughthe top thereof, a movable pipesection hinged to the lower end of said line, means for rigidly securing said pipe section with respect to said line, and means for retaining the pipe section in elevated position. I I,

In testimony whereof, I: havejsubscribed 1 RGE K NG-Q 1 which extends apair of lugs 13, These lugs I are perforated as at 1145;," The lugs 13 are spacedapart, as bestshownin Fig. 4, to receive between them the lug 9 on the flange on thelower end of'the main section of the I charging and suction line and a bolt or pin 15 extendsthrough the perforations in the lugs :of the respective flanges so that the movable section 11 is hinged to the stationary section' 'of-thes'uction and charging line;

' When the still 's being operated, the two -flanges are firmly united by bolts 16 extending therethrough and provided with suitable nuts." A chain 17 which may 'be'in' the form -that,whenfthe movable line section is swung up to substantially horizontal position, as shown in dotted lines in Fig. 1, it may be re;

After the cleaning operation is completed,

.the end of the movable section'is released. from thelfloop, and the section is dropped to I 1 vertical position, in which the flange on the upperend thereof is. in contact'with the f flange offthe lowerfend of the stationary v sectioniofthecharging and suction line, and j thesecuring' bolts are then replaced so that *the structureis in condition for operation; "QIclaimr 1.,In an apparatus of the class described, a still shell, a charging and suction line extending into the shell, a flange onthelower end of said line having a lug thereon, a movableline section having 'a'flange and lugs on Y the upper end thereof, a pin"extending through the lugs and removable bolts extend I ing through the flanges and holding them in fixedrelation.' p f r
